Ecosystems
The type of primary productivity that can be eaten by the next trophic level, after accounting for respiration by producers
What is net?
Species richness tends to increase going towards this place on the globe.
What is the equator? (latitudinal diversity gradient)
Succession of organisms on dead organic material
What is Degradative succession?

Unstable
What is the middle equilibrium/C?
Disturbances hit this trophic level harder
What are predators?
This metric describes not the number of species, but how it is distributed across areas
What is evenness?
Species replacements caused by changing external geophysiochemical forces.
What is Allogenic Succession?
If dN/dt = rN
What is exponential growth?
These types of communities tend to be composed of the best competitors in a given environment, often K-type species.
What are climax communities?
This is a reason why species diversity does in fact not actually correlate with primary productivity
What is high productivity drives fast growth so niche space fills up and competitive exclusion occurs rapidly before the next disturbance?
The two mechanisms of secondary succession
What are inhibition and tolerance?
An example of measuring this is if we find that a small change in juvenile survival markedly affects population growth, so juvenile survival might be a target for conservation efforts.
What is elasticity?
This type of competition is due to a shared predator
What is apparent competition?

I want to test the interaction between the two different types of competition on a prey animal's population size. So I pick these two key factors
What are predator abundance and resource abundance?

Equilibria
Though I haven't tested the oxygen levels to see if they are actually very low, its green hue suggests this is happening in the creek (if we can even call it that?) in the Arb.

What are predator-controlled region, prey have escaped predator control region, and break point?
